 Integral of cos(x)^2 :
02-02-2008
So this was a question in an assignment I handed in today...I couldn't get it then and I still haven't gotten anywhere after 10+ attempts.
(Integral) cos(x)^2 dx
I used integration by parts and I ended up having to find the integral of sin(x)^2 dx which just leads me back to the original integral...any ideas? >_< |
